[SG Politics] How many ministers does Singapore have?

I continue to be amazed by the utter waste of tax-payer monies that goes to pay the ministers who, on the face of it, do nothing. There are ministers with specific portfolios like defence, education, home affairs, law, etc, and a whole bunch of them without any – see the ones in the “Prime Minister’s Office”. The PMO has a minister mentor, two senior ministers, two deputy prime ministers, three ministers without portfolio (whatever that is) – all in about 9 including the PM. Why? If all the ministers are paid S$1m a year, that is S$9m just for the PM’s office? Why? Is paying oneself enormous amounts a halal form of bribery?
